6.4.3
DISPLAY - 3
Function - 31
The large 17 mm digits can be set to display total or flow rate digits at operator level. When total is selected, both total and
flow rate are displayed simultaneously. When flow rate is selected, total will be displayed after pressing select.

POWER MANAGEMENT - 4
As the F110 is normally battery powered, the user will have the concern of reliable measurement over a long period of time.
The F110 has several smart power management functions to extend the battery life time significantly. Two of these functions
can be set:
LCD refresh - 41:
The calculation of the display information influences the power consumption significantly. When the application does not
require a fast display update, we advise you to select a slow refresh rate.
NOTE:
No information will be lost; every pulse will be counted and the output signals are not influenced.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec.
Example: battery life time with a coil pick-up and FAST update: About 3 years. Battery life time with a coil pick-up and 1 sec
update: About 8 years.
Please note that after a button has been pressed by the operator, the display refresh rate will be FAST during the initial 30
seconds.
Battery mode - 42:
The unit has two modes: operational or shelf. When shelf is selected, you can store the unit for several years; it will not count
pulses, the display is switched off but all settings are stored. In this mode, power consumption is extremely low. Normally, the
mode will be operational.

FLOW METER - 5
Signal - 51:
The F110 is able to handle several types of signals. The type of flow meter pickup / signal is selected in software with SETUP
51.
